Aaron 1v. "HORNUNG, 01? Los ANGELES CALIFORNIA COLD-STORAGE-DOORADJUSTABLE HINGE.

To all 1w hom it may concern Be it known that I, ANTON N. HonNUNG, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented a new and usefulCold-Storage-Door Adjustable Hinge, of which the following 1s a Coldstorage door closures are necessarily thick and heavy and are requiredto close tightly upon gaskets. Said closures are constructed with anoutside flange to rest upon a gasket that surrounds the orifice intowhich the main body of the closure extends; the outer portion of theclosure projecting over the face of the casing around the openin n inobject of this invention is to provide a hinge for doors of this kindwhich may be easily applied in hanging the door when the closure is setin position, and which will invariably hold the closure to true posi- Ition when the door is closed and locked or latched, and which will allowthe door to be freely opened without interference from the flange thatprojects to cover a portion of the casing outside of the opening whichthe closure is intended to close.

I accomplish this object by providing a hinge comprising a mountingadapted to be attached to the casing, a mounting adapted to be attachedto the closure, a coupling pivotally connected to said mountings, andadjustable means adapted to cooperate with the pivot of the mounting onthe door closure to hold the coupling in rigid relation to the closure.

The invention is capable of embodiment in various ways and I do notlimit myself to any specific embodiment although the invention includesa specific embodiment which I shall more particularly set forth andclaim herein.

Objects of the invention are simplicity of construction and ease ofadjustment.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description and theappended claims.

The accompanying drawing illustrates the invention.

Figure 1 is a view of the invention applied to a cold storage door,which is shown closed and latched.

Fig. 2 is an enlarged fragmental view of one of the hinges shown in Fig.1.

Specification of Letters Patent.

] Application filed March 2, 1920. Serial No. 363,093.

Fig. 3 is a fragmental' sectional elevation showing the hinge in use inconnection with a cold storage structure. .Line a Fig. 2 indicates theplane'of section.

Fig. 4: is a perspective view of the hinge detached. r

The mounting 1 is adapted to be attached to the casing 2 and comprises abase plate 3 secured by screws 41 to the casing 2 and provided with lugs5 having bearings 6 for the hinge pin or pivot 7. The base 3 is in twoparts and each part is provided with apair of pintle lugs 5 and bearings6. The closure mounting 8 is preferably formed with a base in the formof a strap 9 provided with lugs 10 having holes 11 that act as bearingsfor the coupling pivot 12. The coupling 18 comprises a yoke 14 havingend bearings in the form of eyes 15 carried by the pivots 7 and alsoprovided with an intermediate eye or bearing 16 for the pivot 12 of thecoupling bearing. Said yoke is provided on opposite sides of the eye orcoupling bearing 16 with set screws 17, 18 adapted to engage the closuremounting; and, in cooperation with the coupling pivot or pin 12,affording means to hold the coupling in rigid relation to said closuremounting.

Jam nuts 19, 20 on the set screws fix said set screws in the adjustedposition.

Said set screws are threaded through the coupling on opposite sides ofthe eye 16. Nut locks 21 are provided upon the set screws between thejam nuts and the coupling to prevent accidental loosening of the setscrews.

In practice,"the hinge parts will all be assembled as shown in thedrawing; that is to say, the casing mounting will be pivoted to the eyesof the coupling and the closure mounting will be pivoted to the eye ofthe closure mounting. Then closure 22 will be inserted in the opening23, the casing mounting will be secured to the casing 22 by suitablemeans as the screws 4, and the closure mounting will be secured to theclosure by the screws 24:- Then the set screws will be adjusted to tightengagement with the closure mounting, thus making the coupling and theclosure mounting rigid to each other. The adjustment of the coupling tohold the closure in position to compress the gaskets 25 may be made atany time when the closure is in closed position.

It is thus seen that by this means it is immaterial to what extent theclosure projects outward beyond the casing, within the range,

of the hinge when free from interference of the set screws and that whenthe set screws are tightly screwed home against the closure mounting,the connection is rigid between the closure and the pivoting meanscarried by the door casing.

The mounting and coupling may be made of malleable castings or maybeotherwise p od ced In the drawings I have shown washers 27 on thepivots or pins to insure smooth operation.

The closure pivot 12 may be removed by driving 'it up thus readilydetaching the closure from the coupling in case it is for any reasondesired so to do.

I Cla m 1. A hinge comprising a mounting adapted to be attached to acasing; a mounting adapted to be attached to a closure and provided withspaced lugs between its ends;

a coupling pivotally connected to the casing mounting; a pivot pivotingthe coupling between the lugs; means on opposite sides of the lugs toengage the mounting; and means comprising a mounting adapted to beattached to a casing; a mount- 'ing adapted to be attached to a closure;a

coupling pivotally connected to the casing -mounted and to the closuremounting; and

set screws on opposite sides of the bearings of the closure mounting tohold the coupling in rigid relation to said door closure.

3. The combination with a yoke having at its ends two hinge bearings andhaving intermediate said ends a hinge bearing a door mounting, pins fortheterminal bearings of he y ke and a pin fo e inte ediate hinge bearingof the yoke; said yoke being provided with a tongue; and set screwsthrough the yoke and tongue respectively to hold the yoke in rigidrelation to the door mounting. r V

In testimony whereof I have hereunto set my hand at v.Os Angeles,California, this 20th day of February, 1920,
